| description | The utility model discloses a mechanical sealing structure used for a high-pressure deep well water pump. The mechanical sealing structure comprises a sealing sleeve in sleeve joint with a motor shaft. The sealing sleeve is internally provided with a cooper sleeve in interference fit with the sealing sleeve. The cooper sleeve is in clearance fit with the motor shaft. The end portion, away from a water pump body, of the sealing sleeve is fixedly connected with a sealing end cover in sleeve joint with the motor shaft. The sealing end cover and the sealing sleeve are form to be an annular sealing chamber around the motor shaft. Inside the annular sealing chamber, mechanical sealing movable rings and mechanical sealing fixed rings are clamped and pressed between the copper sleeve and the sealing end cover and are installed on the motor shaft in a sleeving mode. The mechanical sealing fixed rings are in clearance fit with the motor shaft. The mechanical sealing movable rings are in interference fit with the motor shaft. End surface sealing is achieved among the mechanical sealing movable rings and the mechanical sealing fixed rings. The mechanical sealing structure used for the high-pressure deep well water pump has long service lifetime. |
